FMS is not going to happen. There is no need to buy new airframes! A great many 'D's are rebuilt 'A's -fuselages gutted and then rewired to the latest spec. That is what will happen with the Westland 'D's -retain airframe and engines -install new for the rest. The engines themselves don't need an upgrade -there is extra power that could be gained but there is no need for it! They are not looking to carry anything larger or heavier than what they already have.
